Abstract

Material innovation in the manufacturing and automotive industries plays an important role in improving engine performance and durability. Conventional materials such as steel and aluminum have limitations in resistance to extreme temperatures and wear, so new materials such as high-performance metal alloys, carbon fiber composites, and nanotechnology-based materials are developed as solutions. These materials are capable of improving energy efficiency, reducing weight, and extending component life. However, the adoption of new materials faces challenges such as high production costs, fabrication complexity, and validation in real operational environments. Therefore, collaboration between academia, industry and government is needed to develop solutions that are not only technically superior, but also economical and sustainable. This research uses the SWOT method to analyze the strengths, weaknesses, opportunities, and threats in the application of new materials. Data were obtained through literature studies, laboratory experiments, and expert interviews. The analysis results show that materials such as carbon fiber composites (CFRP) have advantages in fuel efficiency and corrosion resistance, but also face challenges in production and maintenance costs. With innovations in manufacturing technology and a more sustainable approach, new materials have the potential to be the optimal solution for the automotive and manufacturing industries in the future

Abstract

This study discusses the paradigm shift in mechanical engineering due to the adoption of 3D printing technology as part of the industrial revolution 4.0. This additive manufacturing technology offers advantages in terms of design complexity, production efficiency, and cost flexibility, but also raises technical challenges such as material anisotropy, surface roughness, and process parameter control. Through a descriptive qualitative approach based on literature studies, this study explores the impact of 3D printing on the structure of the manufacturing industry, performance-based design, and the need for reform in engineering education. Data sources are taken from scientific journals, academic books, and technical reports from the last decade (2014–2024), with a thematic analysis of technology applications, implementation challenges, and implications for mechanical engineering curricula. The results show that although 3D printing has fundamentally changed the design and production process, its integration into the industry is still limited by conventional supply chain structures and lack of human resource readiness. This study emphasizes the importance of transforming the engineering education system towards a digital-based interdisciplinary approach, as well as the need for critical and contextual technology adoption. Thus, 3D printing does not only act as a production tool, but also as a catalyst for systemic change in mechanical engineering and manufacturing.

Abstract

The availability of equitable and sustainable energy in remote areas is a major challenge for national development, primarily due to limited infrastructure and electricity access from conventional grids. Hybrid energy systems that combine renewable energy sources such as solar, wind, and microhydro with energy storage or diesel backup have emerged as an adaptive solution to address energy needs in off-grid areas. This study uses a qualitative approach based on literature to explore relevant hybrid energy system integration practices, challenges, and models across various geographic and social contexts. The study identifies that the success of hybrid system implementation is determined not only by its technological configuration but also by local social, economic, and institutional factors. Technological advances such as the Internet of Things (IoT) and smart energy management systems have contributed to improving system efficiency and reliability. However, obstacles remain in the form of limited funding, low public energy literacy, and weak supporting policies at the regional level. Through a thematic synthesis of the literature from the past five years, this study formulates a local energy ecosystem-based integration model that encompasses modular technology, multilevel policies, and community empowerment. These results are expected to serve as a strategic reference in promoting a just and sustainable energy transition in underdeveloped regions.
